Application filed anuary 28, 1916. Serial No. 74,907.

10 all whom t may concern Be it known that we, CHRISTOPHER S. SroFroRDand FREDERICK IV. JONAS, citizens of the United States, residing atSturgis, county of St. Joseph, State of Michigan, have invented certainnew and useful Improvements in VVheel-Attaching Devices, of which thefollowing is a specification.

This invention relates to improvements in wheel attaching devices.

Our improved wheel attaching device is especially designed by us for useon carriages, such as childrens carriages, although it may be readilyadapted for use in other relations.

rIhe main objects of our invention are: First, to provide an improvedwheel attaching device which is effective and at the same time simple instructure and easily manipulated to secure or release the wheel. Second,to provide an improved wheel attaching device which is compact and doesnot detract from the appearance of the carriage and which also serves asa thrust collar for the wheel.

Further objects, and objects relating to structural details, willdefinitely appear from the detailed description to follow.

We accomplish the objects of our invention by the devices and meansdescribed in the following specification. The invention is clearlydefined and pointed out in the claims.

A structure which is a preferred embodiment of our invention is clearlyillustrated in the accompanying drawing, forming a part of thisspecification, in which:

Figure I is a detail inside view of a structure embodying the featuresof our invention, the aXle being shown in section on a linecorresponding to line 1-1 of Fig. III. Fig. II is a front perspectiveview of our improved wheel attaching device removed from the aXle. Fig.III is a detail view, partially in section, on a line corresponding toline 3-3 of Figs. I and IV. Fig. IV is a detail section on a linecorresponding to line 4 4 of Fig. III. Fig. V is an enlarged detailsection corresponding to line 55 of Fig. I, showing details of the wheelattaching means.

In the drawing, similar reference characters refer to similar partsthroughout the tle arrows at the ends of the section lines.

Referring to the drawing, the axle 1 is provided with a spindle Q. 'Ihehub 8 of the wheel is provided with a fiange 4 at its inner end. Acollar 5 is sleeved upon the spindle of the axle and is provided with anintegral rearwardly projecting attaching arm 6 having flanges 7 at itsedges embracing the axle, the arm being secured by means of the rivet S.The collar 5 is, in practice, preferably a sheetJ metal stamping, theattacliling arm being formed integrally therewit At one side the collaris provided with an integral projecting pivot ear 9, the ear beingforwardly offset so that the flange engaging latch 10 is supported in aspaced relation to the collar to receive the flange of the hub between.The latch member l0 is formed of wire and is provided with an eye 11 forthe pivot 12. The swinging end of the latch member is provided with aloop 13, the end of the loop 14 being in sliding engagement with therear side of the collar and constituting a spring for retaining theSOlatch member in its adjusted position. The collar is provided with aforwardly projecting flange 15 opposite its pivot ear and the latch isheld in frictional engagement with the edge of this flange by means ofits spring loop 13.

The flange is provided with stops 16 which limit the movement of thelatch. The collar is preferably provided with a lug-like keeper 17 whichis struck up from the latch so that the end of the spring loop snapsover this lug when the latch is in its flange engaging position and isthereby effectively retained in that position.

To release the wheel it is only necessary to swing the latch member tothe position shown in Fig. II and it is quickly engaged with the hubflange by swinging it to the position shown in Figs. I, III, IV and V.

IVith the parts thus arranged, `our improved attaching device serves asa thrust collar as well as a means for retaining the wheel. It is verysimple and economical to produce and is easy and convenient to manipulate and, further, is neat and attractive in appearance.

Having vthus described our invention,

engaging latch member pivotally mounted 7 on said pivot ear to swing insliding engagement with said flange between said stops and having a loopat its swinging end disposed with the end of the loop engaging the rearside of the collar and constituting a latch retaining spring, saidcollar having a keeper lug struck therefrom and over which the retainingspring engages when the latch member is swung to its hub flange engagingposition.

2. In a structure of the class described, the combination with an axleand a wheel hub provided with a flange at its inner end, of a collarsleeved upon and secured to said axle and having an integral offsetpivot ear and a flange disposed oppositely to said pivot ear andprovided with spaced stops, a hub flange engaging. latch memberpivotally mounted on said pivot ear to swing in sliding engagement withsaid flange between said stops and having a loop at its swinging enddisposed with the end of the loop engaging the rear side of the collarand constituting a latch retaining spring and a keeper coacting withsaid latch when it is in engaging position.

3. In a structure of the class described, the combination with an axleand a wheel hub provided with a flange at its inner end.

n of a collar sleeved upon and secured to said axle and having anintegral offset pivot ear and a flange disposed oppositely to said pivotear and provided with spaced stops,

a hub flange engaging latch member formed of wire pivotally mounted onsaid pivot ear to swing between said stops, and means for'retaining said'latch member in its adjusted positions.

t. In a structure of the class described, the combination with an axleand a wheel hub provided with a flange at its inner end, of a collarsleeved upon and secured to said axle and having a pivot ear and spacedstops disposed oppositely to said pivot car, and a hub flange engaginglatch member formed of wire pivotally mounted on said pivot ear to swingbetween said stops and having a loop at its swinging end disposed withthe end of the loop engaging the rear side of the collar andconstituting a latch retaining spring, said collar having a keeper lugstruck therefrom and over which the retaining spring engages when thelatch member is swung to its hub flange engaging position.

5. In a structure of the class described, the combination with an axleand a wheel hub provided'with a flange at its inner end, of a collarsleeved upon and secured to said axle and having a pivot ear and spacedstops disposed oppositely to said pivot ear, a hub flange engaging latchmember formed of wire pivotally mounted on said pivot ear to swingbetween said stops and having a loop at its swinging end disposed withthe end of the loop engaging the rear side of the collar andconstituting a latch retaining spring and a keeper coacting with saidlatch when it is in engaging position. In witness whereof we havehereunto set our hands and seals in the presence of two witnesses.
